Coli bacteria conducted by the EPA, The push to remove lead from faucets has resulted in faucets designed to keep water inside the faucet from touching brass.
This prevents lead from leaching into drinking water but also keeps the water from coming in contact with the anti-microbial effect of copper in the faucet's brass alloy. With fast-flowing water inside your faucet, bacteria are usually not a problem. The bacteria simply washed away. But, when the water slows or stops flowing it can collect as tiny static pools inside your faucet.
Water supplies to your house are usually treated with a chemical, typically chlorine, to kill germs but it does not kill every germ, so there are always some microorganisms in your household water. These are species that can live with great contentment on the inside surfaces of your faucets, where some of them build up "biofilms" — often appearing as colored slime — that water flowing at low volume cannot easily dislodge.
It has been known for years that the style of a faucet can have an impact on bacteria growth. High-arc faucets, for example, are known the harbor germs at the high arc of the spout, where water flow is slowest.
In fact, any place inside the faucet where water flow is slowed can become a breeding ground for bacteria. That faster water flows reduce pathogens in faucets was shown by a study by Nakamura et. Note 1. A study in an Italian hospital reported in the February issue of Infection Control and Hospital Epidemiology found that bacteria tend to build up in the pool that collects behind aerators.
Note 2 The study found that the microbial buildup in the faucet was ten times greater than in the water pipes supplying the faucet and that these microbes included the bacteria that cause Legionnaires Disease. Removing the aerators to increase water flow significantly reduced contamination. In researchers at Johns Hopkins Hospital in Baltimore found electronic hands-free faucets, which flowed at a much slower rate than manual faucets, were twice as likely to harbor harmful bacteria than manually operated faucets.
Note 3 Flushing the faucets with chlorine reduced but did not eliminate the contamination. The hospital, which had begun to install hands-free faucets in a new wing in response to reports that showed a potential for faucet handles to harbor bacteria, reversed course and removed all of its electronic faucets.
The Legionella bacteria were found in a faucet near the patient's room and in two other faucets in the hospital. More recently, in November , an outbreak of Legionnaires Disease in a Syracuse, New York hospital was traced to low-flow faucets installed in a new wing of the hospital to reduce water consumption.
So far the problem with pathogens in faucets has not caught the public's attention and faucet companies are doing little to address the potential problems. While some faucet manufacturers are starting to add anti-microbial materials and coatings to faucets but the purpose of these agents is less to combat disease than to make the faucet easier to clean. Any germicidal effect is coincidental but desirable. The proprietary formula reportedly will not "wash off or wear away with normal use.
We suspect that the "proprietary formula" probably contains a lot of copper. The best prevention, however, is developing good water safety habits, including the following:.
Nakamura, Y. Christina, Maria Luisa et al. Sydnor, Emily R. In our reviews and ratings of faucet companies, we will note the companies that comply with the California flow requirements in reports published after July In faucets sold in North America, there is a flow rate to suit just about any regulation.
If a lower flow rate is required, then a device called a flow restrictor is inserted somewhere in the water channel to further restrict flow. It is often a part of the aerator. Its job is to fill the tub. If your tub holds 50 gallons, then that's the amount of water it will take to fill the tub. Filling it more slowly does not save any water but does greatly increase irritation. The flow rate is, therefore, unrestricted except by the size of your water pipes, which usually impose a maximum flow limit of about 5 gpm, at best.
L ead in drinking water is toxic. Infants and children who drink water containing lead could experience delays in their physical or mental development and show deficits in attention span and learning abilities. Water treatment facilities are strictly regulated for the amount of lead they can have in their drinking water, so if your water is rated safe, it has little lead.
But, lead can also get in your water by a process called leaching by which water picks up small amounts of lead by coming in contact with lead sources in your household plumbing. While there is very little lead in most household water, even tiny amounts of lead ingested over a long period of time can be harmful. Fortunately, there are things you can do to reduce even this modest exposure to lead.
Learn more about how we use, and waste, household water at Saving Household Water. Before , brass in faucets in the U. The usual slow action by Congress to strengthen national lead-free standards prompted some states to pass laws that more stringently limited lead in water-supply fixtures. California's AB enacted Section of the California Health and Safety Code that mandates lead content of less than a "weighted average" of 0.
Finally, in a mildly embarrassed Congress got off its duff and stiffened the federal lead-free requirement. The new federal standard contained in Section d of the Safe Drinking Water Act , effective as of January 4, , reduces allowable lead content from the former 8.
Manufacturers have dealt with the lead problem in several ways. The water never touches metal, so it cannot pick up any lead. Plumbing codes also require a second test for what is called "leaching". As water passes through a faucet, it can pick up minerals from the faucet through a process called leaching, including about 1, potential toxins — metals, chemicals, viruses, and microbes of all sorts. All of these have to be screened for and if found, other tests are conducted to see whether they are present in amounts considered unsafe.
If this sounds like a lot of tests, it is. And, it still may not be enough. New chemicals are being created every week. A study by the U. Geological Survey of 25 water utilities around the county found 18 chemicals in drinking water that are not currently regulated but could be dangerous including a herbicide, eleven fluoride compounds, two solvents, caffeine, and the commonly prescribed antidepressants: Effexor venlafaxine , Wellbutrin bupropion , and Celexa citalopram.
Lead is the metal of most concern because it is the toxic metal most likely to be in your faucet. There is no safe level of lead. And, unfortunately, there is no way to avoid it. It's in the food we eat and the air we breathe. What regulators try to do is limit your exposure to lead, especially in drinking water. That is not very much lead. In fact, to ingest a single gram of lead from a certified low-lead faucet you would have to drink about , gallons of tap water.
Since the average person consumes only 30, gallons of water in his or her lifetime, it may take quite a while to drink that much water.
Testing for lead leaching requires a three-week evaluation using water that is more corrosive than the average drinking water. Its study showed that there could actually be as much as 48 ppb lead in drinking water that has been sitting inside a faucet, even though the average of water flowing through the faucet tests at below 5 ppb. For that reason, it suggests allowing a faucet to run for a few seconds before drawing water for drinking and cooking.
Lead is so toxic to children that AAP recommends 1 ppb for faucets install in schools. Other metals that are not particularly toxic but which could affect the taste or appearance of water, like nickel and copper, are tested against maximum allowable concentrations. Old pipes are the culprit. They were often made of lead, and even after copper became the standard, it was usually soldered with lead solder until lead in solder was outlawed in If your old house water pipes are galvanized steel or black iron, they probably have several problems by now but none of them is lead contamination.
Plastic pipes are safe from lead but have several other problems, and cannot be used in many localities, including most places in Nebraska that aren't farmland. The answer may be PEX, an engineered material made of cross-linked polyethylene formed into a hose. Stronger and more flexible than copper, and less susceptible to damage from freezing, it has gained widespread acceptance in the plumbing trades for most household water supply applications.
One faucet company, bypasses the lead-in-brass problem altogether by running witter through its faucets in a pex tube. Since the water never touches brass, it cannot pick up any lead.
Testing and Certification is costly. The difference is largely the expense of initial certification and the ongoing cost of maintaining certification. But, since faucet certification lists are public documents, it's simple to find out which companies are cheating. Companies that sell uncertified faucets are identified in our reviews.
We base our conclusions on the status of a company's certifications on public records published by each certifying agency. A company that does not own a public certification listing is not selling certified faucets no matter how loudly it claims that it is. Wald, Matthew L. Raloff, Janet "Lead-free? PEX is flexible cross-linked polyethylene tubing used in plumbing to replace copper pipes. It can be bent around curves, so fewer joints are required. Joints are always a potential source of leaks.
While lead gets all the publicity, NSF 61 actually requires testing for the presence of about 1, substances including metals, chemicals, and organic compounds. The testing is in two parts. The first part determines whether a banned substance is present in the water passing through a faucet in any measurable amount. If it is, then a second test determines whether it exceeds the maximum amount set out in the standard. If so, the faucet fails and will not be certified.
Quick Guide to U. Plumbing Codes. All plumbing codes in effect in the U. Faucets that do not meet these standards cannot be lawfully installed in a home water system anywhere in the U.
Model Plumbing Codes. Plumbing Codes by State. Table Footnotes:. Purpose or Objective. Prohibited from being imported, held for sale or sold. Only - Canadian sales are not affected Illegal for installation in a drinking water system. Energy Policy and Conservation Act. Who Enforces Faucet Safety? Federal Enforcement Certain requirements are a matter of federal law and have a national scope.
The term "introduce into commerce" is defined as "to sell in commerce, to import, to introduce or deliver for introduction into commerce, or to hold for sale or distribution after introduction into commerce.
Insurance Companies The final enforcement arm is your insurance company. De-Mystifying Certification Marks A faucet that is tested and certified will not just be listed on a "Certificate of Listing", it must also bear the mark of the certifying organization. Underwriters Laboratories UL Faucets displaying the UL mark have been evaluated and found to comply with all applicable nationally recognized health effect and performance standards, and have demonstrated compliance with both the IPC and UPC plumbing codes.
